[0002] Hard roof is an important classification of traditional ancient building roof. The current typical ancient building hard roof structure in southern region usually includes, from bottom to top: 1. bearing layer: purlin (Φ120-180mm round wood) with 600-900mm spacing; 2. base layer: rafter board (30×100mm fir strip), bottom tile (210×140×9mm) is laid in "press five leave five" way, with overlapping length ≥70mm in water direction; 3. waterproof layer: tile (230×230×9mm) is overlapped with seven tiles and three tiles left, and cylindrical tile (Φ80mm) is fixed with grass-ash; 4. auxiliary layer: cylindrical tile surface is wrapped with grass-ash mortar.

[0003] Based on the above, the traditional technology has the following problems: 1. Insufficient waterproof performance: the rafter board spacing in the traditional "press five leave five" way leads to a high rainwater penetration rate of 15-20L / (m²·h), and the tile overlapping part only relies on grass-ash bonding, and the bonding strength decays to 40% of the initial value after freeze-thaw cycle.

[0004] 2. Acoustic defect: rain noise sound insulation is only 25dB, and structure sound transmission is significant.

[0005] 3. Structure durability problem: the annual average corrosion rate of wood rafter board in the environment with humidity >65% is 1.2-1.8mm / year, and the present application uses multiple waterproof processes to reduce the moisture, dry-wet alternating conditions of wood rafter board, so as to improve the structure durability.
